Method for establishing a hold state of a connection between two terminals

The invention relates to a method for manufacturing a holding state ( "Park") a connection between two Wählanschlüssen according to the Preamble of claim 1st

The feature "Parking" is already on digital ISDN connection and realized in PBXs. It allows the user, a existing, continuous or future communication link in a Holding state to bring ( "Park"), the call party a Announcement or music on hold (music on hold) receives. In holding state , any tampering with the terminals of the initiating Connection to be made, which in the normal state of lead compound to clear the connection, for example, replacing the Telephone handset and pulling out of the terminal of the junction box. Of the User at the initiating subscriber, for example, his listeners hang up to go to another terminal, or terminal of the to separate junction box and at another location at a Connect communication box. By renewed seizure of Connection, for example by lifting the handset, and optionally Typing procedure is the call on hold again back parked and terminates the hold state.

A user at the analog select terminal must present a costly implement and expensive solution via the switch AWADo / T2 / T4, a connection from a terminal to another terminal to fold. In addition, an automatic switch over this Connection can be allocated only if by acclamation another Person occupancy prepared at the desired terminal, for example by Picking up the handset. Only after that is by laying on the original terminal connected through the connection to the other. If there is no second person is available, the user needs these Operation relatively cumbersome itself gradually perform. in addition is that these automatic switches through their switching behavior and the different conditions lead again Problems are. Plugging a terminal of a Junction box to another junction box is not in principle possible because of the disconnection of the immediately after removal Terminal to the telephone socket is triggered.

The invention is therefore based on the object to provide a method, at the analog Wählanschlüssen the easy production of a temporary holding state ( "Parking") a communication link allows, in which manipulation of the terminal, in particular replacing the receiver and the stripping of the terminal to of the junction box, do not cause the degradation of the compound, so that the Communicate with the caller through another terminal or can be continued at a different location.

The object is achieved by a method for producing a Holding state ( "parking") of a compound according to the preamble of Claim 1, which is characterized in that the initiating Terminal is an analog connection and the method at least following, automatically one after running the steps of:<sl><li>a) the process is controlled by a control signal generated by a Activation procedure, eg by keyboard input, at a terminal of the is initiating subscriber generated and detected by the network node, started;</li><li>b) within a predetermined time interval .DELTA.t receives the network nodes Connection from the initiating terminal to the waiting connection, upright, ignoring signals in the disconnect trigger normal state and by deactivation of the initiating Terminal used connection be effected;</li><li>c) the network node detects a restocking at the initiating subscriber and</li><li>c1) at of performed within the time interval .DELTA.t Restocking the held call from serviceable to the initiating terminal by turns or</li><li>c2) the compound waiting for initiating connection degrades, if no new occupancy is detected within the time interval .DELTA.t.</li></sl>

In an advantageous development of the method, an in step c) Recall the initiating subscriber by the network node if within the time interval .DELTA.t no restocking on initiating Terminal is detected. The connection is successful at forming thereupon Restocking of the initiating subscriber station within a time interval .DELTA.t 'From waiting switched through to the initiating subscriber. Otherwise it will be terminated if no reaction on the part of the initiating Connection occurs.

The process is in a telephone network with some analog Wählanschlüssen advantageously a procedure determined that an existing Walking or incoming call in a hold state ( "Park") - similar consultation, brokering - and then brings a certain period of time a temporary disabling devices at initiating subscriber allowed until after a new assignment and optionally enter a procedure ( "Back Parking") which held Connection is again switched through to the initiating subscriber. Becomes the parked call is not within a certain period taken, there is a recall, until finally after a further Period zwangsabgebaut the parked call and Gassenbesetzton is applied.

The introduction of this method for manufacturing the holding state of a Connection ( "Parking"), for example, by triggering a hook flash signal followed by entering one or more Tax code (eg to hook flash, "9"). This gives the now the park located state participants preferably an informational Announcement 9, for example, "Your call is held". The network node or the Exchange builds upon detection of a release operation on initiating the select terminal parked call then not starting. Detects the network nodes on initiating select terminal within For example, At = 30 s a re-enrolling, he turns directly or by entering a special deactivation procedure (eg "* 9 #") the parked call by again. This is the original Connection is restored.

Detects the network nodes within this time interval .DELTA.t, for example, At = 30 s, no re-occupancy, so the connection is zwangsabgebaut. Advantageously, however, the intermediate circuit of a re-call to the initiating subscriber by the network node. If this recall at the initiating subscriber station is not within a further time interval .DELTA.t 'Of example also .DELTA.t' = 30 s assumed solves the network nodes the parked call back and puts the waiting terminal Gassenbesetzton on.

By the method it is possible in an advantageous manner, during a existing connection to use another terminal or in a another room to go. This switching to a fax machine without the loss of the joint made independently or using another terminal, for example, with special features such as Listening, handsfree etc., possible. By entering a Activation procedure, eg the key combination hook flash (HF) and a corresponding tax code, the subscriber may at initiating subscriber this connection "park" and then the just used to disable terminal. A hang-up or pull TAE connection plug does not then, for example, to reduce the Connection. If the customer has his terminal back in to a telephone socket, eg another room, infected and has the connection again or he is his connection again from another terminal, so he accepts the parked connection. The preparation of Normal state, either by simple documents, for example by Picking up the handset, or in addition, by entering a Deactivation procedure (eg * # 9) are triggered. Then there is the Connection with the parked caller again. This process can are often carried out at any time during an existing connection, the roles of the initiating and waiting terminal arbitrarily are interchangeable.

The tariff for outgoing connection is preferably also during the period parked; the correct fee numeration Terminal is not given in this case.

Description of the drawing:

The drawing shows a flow chart of the method according to the invention for the production of the holding state of a compound ( "Park"). Initial situation is an existing communications link between two Wählanschlüssen, one of which as the initiating Port at which parking of the compound is initiated, and the second terminal is referred to as waiting terminal. The Telephone connection is via a network node of the telephone network in usual prepared. The initiating terminal is an analog Select terminal.

Parking the connection between an initiating and wartendem Connection is initiated by a control signal. The control signal is by an activation procedure, eg by keyboard input to a Terminal of the initiating subscriber generated, and the network node recognized. This key combination is, for example, the input of hook flash (HF) and a control code, eg "9".

After initiation of the procedure by the initiating terminal ignores the nodes within a predetermined time interval .DELTA.t Signals that normally trigger the disconnection, the part the initiating subscriber. These trigger signals are from initiating subscriber station usually generated when the handset hook, or the terminal is pulled out of socket. in the Normal state is the connection with the receipt of such trigger signals mined by definition. In holding state is the connection even when from network nodes identified deactivation of the terminal used on maintained initiating subscriber.

If the Call Park initiated by the initiating subscriber, is the person on the waiting terminal an outgoing message or Music recorded by the network node.

The network node detects a restocking at the initiating subscriber, eg by resuming the handset or terminal and activate a another terminal. Optionally, the restocking must by Deactivation procedure such as a keyboard shortcut and HF Tax codes are acknowledged.

If within the time interval .DELTA.t a restocking on initiating Terminal, the node switches the connection from waiting for initiating subscriber free. Communication can in the usual Way to be continued, the disconnect is in the usual manner triggered by hanging up or disable the terminal and the connection is terminated by the network node. The existing Communications link can be parked as often, which also the roles of an initiating and wartendem terminal are interchangeable.

Detects the nodes within .DELTA.t no restocking on initiating Connection, it automatically calls to the initiating subscriber. To this , The subscriber will be remembered at the initiating subscriber because he meantime the connection with its communication partner had parked.

If the recall is a reaction to the initiating subscriber within a time interval .DELTA.t ', the network nodes on the connection between wartendem and an initiating terminal again by, and the Communication can be continued.

Detects the network nodes within the time interval .DELTA.t 'no reaction on initiating subscriber, for example, by recording the handset or response the fax machine, so he sets up the connection to the initiating terminal Reverses. At the waiting terminal of Gassenbesetztton is issued, indicating the waiting caller that the Communication link to his interlocutor now is canceled.
